First service
"Rathbod, Im afraid you are wrong."
Barchetta, fully understand your response if that is what is in your service book, but (lets be quite specific and sure) if it is "the" manufacturers warranty, not a bought in one, say on a used vehicle, my note earlier this morning is correct.
The folloiwng Web IP addresses may assist in reassuring you
http://www.theaa.com/motoring_advice/general-advice/car-servicing-and-repair-faqs.html
This site (above) is the Q&A's on the AA, scroll down to the question "Do I have to get my car serviced by a main dealer?"
http://www.smmt.co.uk/consumeraffairs/dsp_faq.cfm?catid=914&fid=20&fid1=&fid2=&maincatid=913&sid=136&tsid=135&cacatid=P_3360&chosenqa=263#263
This site is the comsumers advice section at the SMMT (Society of Motor Manufacturers and Traders).
By the way the last Web site, again just to hopefully re assure you, is the VW on line details of the warranty on their cars.
http://www.volkswagen.co.uk/owners/warranty/factory/terms
You will note they advise of having the vehicle serviced in accordance the manufacturers recommendation.
Hope this helps
